Senior SoC Subsystem & IO Architect — Next‑Gen AI HW

NVIDIA Corporation; California; On-site; USD 184,000 - 357,000; Full time

Job summary

NVIDIA Corporation is seeking a Senior SoC Subsystem & I/O Architect to join our ambitious LPU team. This role involves defining the high-level architecture for next-generation AI and high-performance computing products, focusing on uncore IPs including PCIe/CXL, NVLink/NVLink-C2C, UCIe, AXI/CHI, NoC fabrics, memory systems, coherency, boot, system initialization and power management.

You will translate product requirements into architectural specifications, craft functional and architectural

Qualifications

• BS/MS/PhD in Electrical/Computer Engineering or Computer Science, or equivalent experience.
• 8+ years of proven experience in SoC/architecture.
• Strong understanding of SoC and uncore subsystems, IO and interconnect cores (PCIe, CXL, NVLink, UCIe, AXI/CHI, NoC).
• Experience translating product requirements into architecture/IP/subsystem specifications.
• Experience crafting functional and architectural models from specifications (C/SystemC).

Responsibilities

• Define high-level SoC subsystem architecture for LPU products.
• Convert product requirements into architectural specifications for uncore, IO, memory, firmware-facing, boot, reset, safety, fault tolerance, diagnostic, and power regulation subsystems.
• Collaborate with IP teams to develop build documents for PCIe/CXL, NVLink/NVLink-C2C, UCIe, AXI/CHI, NoC fabrics, memory controllers, coherency blocks, MMUs/IOMMUs, boot, reset, and associated SoC infrastructure.
• Specify subsystem behavior including enumeration, capability discovery, configuration flows, sequence control of memory operations, data consistency, address mapping, interrupt handling, virtualization, error handling, and firmware/software-visible controls.
• Build or guide functional and architectural models from specifications, using C++, SystemC, Python, or similar languages.
• Use models to validate architecture intent, subsystem behavior, configuration sequences, and IP interactions before RTL or silicon is available.
• Drive tradeoffs across bandwidth, latency, power, area, timing, scalability, reliability, security, debuggability, and software usability.
• Review IP specifications, subsystem architecture documents, model behavior, verification plans, and validation strategies.
• Collaborate with architecture, IP, firmware, software, RTL, verification, platform, and post-silicon teams to bring architecture decisions to completion.
